  1. Science Vocabulary Using word parts to facilitate meaning

  2. Derivation of Many Science Terms • From two ancient languages • Greek • Latin • A list of these is inside the front cover of the Martini text

  3. Did you know that many science terms are “built” from word parts?

  4. Derivation from Greek Word Parts • Did you know? • Biology • Bio = life • Logy = the study of • Biology = the study of life

  5. Derivation from Latin Word Parts • Bilingual • Bi- = two • Lingu/o = tongue, language • -al = pertaining to • Bilingual = pertaining to two languages

  12. Chemistry Terms • Endothermic • Endo- a prefix meaning within • Therm/ a word root meaning heat • -ic a suffix meaning pertaining to • Definition: pertaining to (taking) heat in

  13. A Contrasting Chemistry Term • Exothermic • Exo- a prefix meaning out, outside • Therm/ a word root meaning heat • -ic a suffix meaning pertaining to • Definition: pertaining to (sending) heat out

  14. Another Pair of Chemistry Terms • Homogeneous • Homo- a prefix meaning same, similar • Gene/ a word root meaning kind or type • -ous a suffix meaning pertaining to • A homogeneous solution is made of similar types (of substances)

  15. Another Pair of Chemistry Terms, continued • Heterogeneous • Hetero- a prefix meaning different • Gene/ a word root meaning kind or type • -ous a suffix meaning pertaining to • A heterogeneous solution is made of different types (of substances)

  16. A Closer Look at Prefixes • Ren/o means kidney • Prefixes • Peri- around, surrounding • Supra- above • Infra- below

  17. How Prefixes Change a Term • Perirenal pertaining to surrounding a kidney • Suprarenalpertaining to above a kidney • Intrarenalpertaining to within a kidney

  19. How Suffixes Change a Term • Cephalic = pertaining to the head • Cephalad = towards the head • Cephalalgia = pain in the head, or a headache

  21. How the order of word roots can change the meaning of a term. • Anter/o front • Poster/o back • -ior noun ending • Anterior the front of the body • Posterior the back of the body

  22. How order of word roots can change the meaning, continued • Anteroposterior from the front to the back • Posterioanterior from the back to the front

Awareness of Terms Built from Word Parts • Start your own list of prefixes, suffixes, and word roots for science terms. • Check your dictionary or glossary to confirm meaning. • Begin to reap the rewards of being a more efficient and effective reader with your increased knowledge of scientific terms built from word parts.
